[BNM] Buying a squatted domain

[Ali]

"If an email to the Whois contact fails is there anything else that can be
done to try and acquire a domain?"

because I own no17.org I got an unsolicited email from these folks 

http://www.jeholiahonline.com/domain-testimonials.htm

asking if I wanted them to acquire the .com on my behalf, don't know if they are any good or even follow proper etiquette if there is such a thing.

they said they would charge £500 (on top of the domain costs) for their services.

I declined...
